Abstract
The present invention proposes a kind of civil aircraft main cabin portable directional explosion-proof apparatus structure, including spherical tank main body, strengthens side-panel, and wherein spherical tank main body is three-decker interior, domestic and abroad.Spherical structure main body both sides have a hangers handle respectively, it is simple to the locking of the movement of orienting device, rotation and structure.The present invention is with traditional explosion-protection equipment principle difference: the shock wave that the blast of certain equivalent produces mainly is guided outside aircraft passenger compartment by this directional explosion-proof device, allows energy discharge, and ensures passenger plane and the safety of occupant to greatest extent.Present invention employs quick-release type latch-up structure, corresponding groove is designed in the minimum risk bomb position only need to specified in aircraft passenger compartment, just can be by portable directional explosion-proof device quick lock in the minimum risk bomb position specified.And this device need not design extra hole goes to put into explosive, it is to avoid hole becomes the weak spot of device so that the present invention portable directional explosion-proof apparatus structure is simple, explosion-proof energy is strong, easy to operate.
Description
Technical field
The present invention relates to the airborne vehicles such as civil aircraft safe explosion-proof guard technology field, particularly relate to a kind of civil aircraft main cabin
Portable directional explosion-proof device.
Background technology
In recent years, increasingly serious along with international situation, the attack of terrorism has the sternness spread the most rapidly to become
Gesture, terrorist can choose the terror consequences such as artificial abortion concentrates, bad sues and labours, lethality is big, social influence is extensive all the time
Place implements to attack, to reach fright and to cause the purpose of crowd panic.Commercial aircraft meets all conditions above, is that terror is attacked
The primary selection hit, and the event that improvised explosive devices causes aircraft accident happens occasionally.Although bomb detection technology is not
Disconnected development, but in the case of huge flow of the people and car loading, it is difficult to ensure that perfectly safe.Bomb is it is possible to pass through multiple
Approach is brought on aircraft: as the hand-baggage of boarding passenger, crew, canteen dining car, maintenance and repair personnel, registered luggage,
Goods and airmail etc..For current airplane design, if do not taked special protection and explosion precaution, small amount bomb
Blast all can trigger chain reaction, cause the major disaster of fatal crass.Such as there is the Lockerbie airplane crash in 1988, beautiful
State passenger plane B747 has just taken off soon, and through investigation, in fore hold, about 280 to 400 grams slurry explosiveses are detonated, and aircraft is aloft
Blast is disintegrated.Ultimately result in 259 passenger and crews and 11, ground Lockerbie resident on flight to die an unnatural death.
In the case, propose the flight safety of aircarrier aircraft and flight course are resisted the ability sabotaged
Higher requirement.International Civil Aviation Organization (ICAO), on March 12nd, 1997, has issued International Civil Aviation pact adnexa 8 the 97th
Amendment, it is proposed that civil aircraft considers minimum risk bomb position (LRBL) when design, is found band for placement and boards a plane
Bomb.
For problem above, the technology such as bomb detection technology, cargo hold Explosionproof container and blast resistance construction are abroad carried out
Research work.The Explosionproof container structure wherein invented is applied to aircraft cargo bay more, is applied to aircraft passenger compartment though also having, but knot
Structure weight, is not easy to mobile, operation complexity, and takies bigger passenger space.
Summary of the invention
For solving for technical problems such as civil aircraft main cabin explosion-proof protective device structure weight, operation complexity in prior art,
Being different from traditional energy-absorbing explosion-proof tank structure simultaneously, and do not cause when there are special circumstances passenger panic, the present invention proposes
A kind of civil aircraft main cabin portable directional explosion-proof device.Portable directional explosion-proof device belongs to the one of explosion-protection equipment, but again
Being different from traditional anti-explosion tank, traditional anti-explosion tank principle is that the shock wave and energy produced by certain equivalent explosive charge is by preventing
Quick-fried tank body bears and absorbs.But portable directional explosion-proof device main purpose is to play the effect of orientation and energy-absorbing, by one
The energy that settled amount explosive charge produces is discharged into outside main cabin along structural openings direction, meets portable directional explosion-proof dress simultaneously
Put the requirement occurring without relatively havoc.Ensure aircraft can safety landing and make a return voyage, ensure occupant safety to greatest extent.
Technical scheme is as follows:
Described a kind of civil aircraft main cabin portable directional explosion-proof device, it is characterised in that: include spherical tank main body and strengthen limit
Edge panel；Strengthen side-panel to be weldingly fixed at spherical tank body openings, and strengthen there is tight locking button on side-panel, it is possible to
The locked groove of minimum risk bomb position, civil aircraft main cabin coordinates.
Further preferred version, described a kind of civil aircraft main cabin portable directional explosion-proof device, it is characterised in that: described ball
Shape can body internal layer be wavy metal panel, intermediate layer be porous foam aluminium interlayer, outer layer be metal shell.
Further preferred version, described a kind of civil aircraft main cabin portable directional explosion-proof device, it is characterised in that: strengthen limit
Being evenly distributed some guipures hook in edge panel, spherical tank main body inner bottom part is annularly distributed some guipures hook, described
Guipure is jointly hung with on guipure hook.
Further preferred version, described a kind of civil aircraft main cabin portable directional explosion-proof device, it is characterised in that: described ball
